| Popis: | Understanding the machining process in the microscopic level has been a challenge over the years. Machining process as such is very complex due to various factors, which is involved like friction, plastic deformation, material failure etc. The present works aims at developing a 2D FE model to predict the residual stresses induced after machining operation. Over the years’ lot of development has taken place particularly with the advent of high-end computers and FEM software packages. This works aims at incorporating the developments that has taken place in the field of Finite Element Analysis of machining processes and try to give an improvised model to understand the machining process in a better way. The work also aims at determining the residual stresses that are induced in the material after machining, its nature and magnitude. The influence of machining parameters on the machining induced residual stresses was studied with the help of commercially available software. Present work has been conducted on AISI 1045 steel. Simulations results are in good agreement with the experimental results. |
